Parking garage cleaning: flat-rate decks, drone-cleaned facades

On garages of 100,000 sq ft and up, the deck and drive surface is a flat $0.06 per square foot, not a range, and not adjusted for condition. A 100,000 sq ft garage deck is $6,000, a 150,000 sq ft deck is $9,000, and a 250,000 sq ft deck is $15,000. Walls, columns, ceilings, and stairwells are a separate line item at $0.06–$0.08 per square foot of surface. Below 100,000 sq ft we quote a fixed price after a free site survey instead of publishing a rate, because mobilization is a much larger share of a small garage and a published number would mislead.

Because almost everything that makes facade work expensive is absent. A garage deck is flat, open, drive-on, and reachable at grade. There is no access equipment, no rigging, no working at height, and no elevation-by-elevation sequencing. Our surface cleaners cover ground per hour at a rate no vertical surface can match, so at garage scale the economics are genuinely different from a building envelope. That is also why the rate is only published at scale: the saving comes from volume, not from cutting the process.

No, and any company telling you otherwise is overselling. A garage deck is a covered structure with low clearance and no reliable GPS, the wrong environment for a cleaning drone. Decks, columns, ceilings, and stairwells are cleaned by our ground crew with heated water and rotary surface cleaners. Where the drone does earn its place on a garage is the exterior facade and the open top deck, which we fly in the same mobilization rather than sending a second contractor and a lift.

Yes. Our truck carries a BE hot box heating 8–10 gallons per minute, so chemistry is applied hot rather than cold, which is what makes the difference on embedded automotive residue. Heated surface cleaners plus a degreaser lift drip stains, tire rubber, and traffic film that cold water and chemistry alone leave behind. Deep, long-standing oil shadows in a numbered stall will lighten substantially but do not always disappear entirely. Concrete is porous, and we will tell you that at the survey rather than after the invoice.

One section at a time, and usually not a whole level. We work in coned sections and move as we finish, so tenants and visitors keep using the structure throughout. Most garages are cleaned overnight or across a weekend, when occupancy is at its lowest and drying time is uninterrupted. Full closures are the traditional model because lifts and long hose runs need the space. Our footprint is a crew and a truck, not a staging area.

A 100,000 sq ft deck is typically two to three overnight shifts. A 250,000 sq ft structure runs closer to a week, sequenced level by level so no part of the garage is out of service for more than a shift. Walls, columns, and ceilings add time, because they are hand-worked rather than covered by a surface cleaner. The survey gives you a shift-by-shift schedule before you sign anything.

It is planned before we arrive, not improvised. Garage drains route to the sanitary or storm system depending on the structure, and the survey identifies which. We recover and filter runoff where the discharge point requires it, use biodegradable degreasers, and keep the solids out of the drain with inlet protection. On structures with a documented oil-water separator, we confirm its condition with the property before the first shift rather than assuming it can take the load.

Not with a correctly matched process, which is exactly why the survey matters on a garage. Bare and sealed concrete take heated surface cleaning without difficulty. Elastomeric traffic coatings and waterproofing membranes are different: they need reduced pressure and a neutral-pH degreaser, because an aggressive nozzle will chalk or lift a coating and turn a cleaning bill into a recoating bill. We identify the coating and its condition first and adjust the process to it.

Yes, and this is where the drone works. Garage exteriors collect exhaust soot, salt drift, and biological growth on precast panel, painted concrete, and metal screen, the surfaces the public actually judges the property on. We fly them with low-pressure soft-wash from grade, with no lift blocking a lane and no deck taken out of service. Bundling the facade with the deck in one mobilization is materially cheaper than contracting the two separately.

Yes, as part of the wall and ceiling scope at the same per-square-foot rate. Stairwells are usually the worst-smelling and worst-reviewed part of a garage and the part a property manager hears about most, so they are rarely worth leaving out. They are hand-worked with hot water and chemistry, and we treat them as an occupied interior: controlled water volume, contained runoff, and dry before the space reopens.

We still clean it. We just quote it rather than publish a rate. On a smaller structure, mobilizing the truck, the hot box, and the crew is a much larger share of the job, so a single per-square-foot number would either overcharge some properties or misquote others. The site survey is free and the resulting price is fixed, so a smaller garage costs you a walkthrough to find out. Portfolios of several small garages often price close to the $0.06 rate, because they share one mobilization.

Most structures land on an annual deck wash, with the ground level and entry ramp done twice a year because that is where traffic film and public perception concentrate. Coastal garages within a few miles of the water need the exterior facade more often than the deck, since salt drift drives that surface rather than tire traffic. Garages attached to a retail or restaurant tenant usually move to a semi-annual cycle on the deck.

Yes. $2M commercial general liability plus dedicated UAS aviation liability for the drone portion, with certificates naming the owner, operator, and property manager issued before we mobilize. Drone flights run under 14 CFR Part 107 with an FAA-licensed commercial pilot, and LAANC airspace authorization is filed where a garage sits in controlled airspace near a major airport.

Deck area is the gross drive-on surface of every level, ramps included, taken from the structural or as-built drawings and confirmed on the walkthrough. We do not bill by stall count, and we do not bill the same square foot twice. Wall, column, and ceiling surface is measured separately because it is a different unit of work. A column is hand-worked, a deck is machine-worked. If your drawings are missing, we measure on site and show you the take-off with the proposal, so you can check the number rather than take it on trust.

It is genuinely flat at 100,000 sq ft and up. Condition does not move it, level count does not move it, and a heavier first clean does not move it. That is a deliberate difference from how garage work is normally bid, where a "from" price gets revised upward once someone sees the oil. The rate absorbs condition because at this volume the machine time is the cost, and a dirtier deck does not change how fast a surface cleaner walks. The survey exists to confirm coatings, drains, and access, not to find a reason to reprice.

Included: heated surface cleaning of every deck and ramp, degreaser treatment on oil and tire marks, coned section work so the structure stays open, drain inlet protection and runoff handling, 4K documentation of the finished structure, and a certificate of insurance naming the owner and manager before we mobilize. Separate line items: walls, columns, ceilings, stairwells, and elevator lobbies at $0.06–$0.08 per square foot; the exterior facade; line re-striping; and any recoating of a failed traffic membrane, which is a coatings trade, not a cleaning one.

Yes, and on large structures most owners do. A common split is decks in year one and walls, columns, and stairwells in year two, or ground level and the top deck first because those carry the most visible wear. Phasing costs slightly more in total than a single mobilization, because the truck and crew set up twice. The survey shows you both numbers so the trade-off is explicit rather than discovered later.

Not as part of the cleaning scope, but cleaning is the right moment to decide. Heated surface cleaning will lift loose and already-failing paint, which makes faded striping look worse before it looks better. That is the paint failing, not the cleaning damaging it. If your striping is near end of life we will flag it at the survey so you can line up a striping contractor for immediately after, while the deck is clean and the layout is clearly visible.

The deck rate is already flat and already at the bottom of what we quote for any surface, so a recurring garage schedule does not discount below $0.06. What a schedule does buy is a locked rate across the term, priority scheduling around your events and tenant calendar, and a much lighter clean each visit, a deck on an annual cycle never accumulates the built-up film that makes a first clean slow. The saving shows up in the wall and facade scopes and in not needing a heavy reset.

We do the cones, barricades, and section signage as part of the job. Tenant notice is a joint effort: we give you the shift-by-shift plan far enough ahead that your team can post it through the normal channels, because a notice from the property manager gets read and a notice from a contractor does not. On structures with valet or a parking operator, we build the sequence with the operator directly so stall counts stay workable each night.

Yes, and they are mapped at the survey. EV charging equipment, gate arms, ticket spitters, card readers, cameras, and sub-panels all get no-spray buffers and, where the exposure warrants it, physical covering before water is applied nearby. Anything already damaged or with a compromised enclosure is photographed and flagged to you before the shift rather than after: a pre-existing fault found afterwards becomes an argument, and we would rather it be a record.

4K aerial and deck-level footage of the finished structure, before and after, delivered with the project. Boards and asset managers use it the same way they use the case-study documentation on our building work: to show the spend produced a visible result, and to date-stamp the condition of the deck and the coating. On structures heading into a recertification or an insurance inspection, that record is often worth more than the clean.

Because the proposal is a fixed price, not an estimate, and it is issued after the survey rather than before. The survey is where the variables get resolved (deck area, coating type, drain routing, access windows) so there is nothing left to discover once we mobilize. The only thing that changes a fixed price is you changing the scope. If we get the measurement wrong, that is our error to absorb, not a change order to send you.

Put every bid on the same unit before you compare totals. Ask each contractor for the deck rate per square foot, the deck area they measured, and whether walls, columns, ceilings, and stairwells are in or out. Bids that quote a lump sum without a measured area cannot be compared to anything, and a low lump sum usually means a smaller assumed scope. At $0.06 per sq ft our number is trivially checkable: multiply it by your own deck area and see whether the total matches the proposal.

Because the two ways to make a garage bid cheap both cost the owner later. The first is cutting scope, quoting the deck only, then adding walls, stairwells, and the facade once the crew is on site. The second is cutting method: cold water and high pressure move faster and cost less per hour, but cold water does not lift embedded oil, and high pressure on an elastomeric traffic coating chalks it. A recoat is an order of magnitude more expensive than the cleaning that caused it.

Five questions settle it. What deck area did you measure, and can I see the take-off? Is the price fixed or an estimate? What is your process on a coated deck specifically? Where does the wash water go, and who is responsible if the discharge is questioned? And will you name the owner and the management company on the certificate of insurance before mobilizing? A contractor who cannot answer the coating and the runoff questions has not surveyed your structure.

For the deck, the question does not apply. The deck is ground work either way, and our deck rate is the value proposition on its own. Where the drone changes the arithmetic is the exterior facade. Traditionally that is a second contractor, a second mobilization, and a lift parked in a traffic lane for days. Flown from grade in the same mobilization as the deck, it avoids the lift rental, the lane closure, and the permit cycle entirely.

Yes, and portfolios are where the pricing works hardest. Several garages under one owner or one management company share a mobilization and a schedule, which is what lets structures below the published threshold reach the same rate as the large ones. We sequence a portfolio so no two properties are disrupted in the same week, and issue one consolidated documentation package for the asset file.

Yes. The schedule is built around your calendar, not ours. Retail and stadium-adjacent structures get cleaned mid-week and overnight; office garages are usually weekends; hospital and hotel garages run in small sections continuously because they never really empty. Because we work section by section rather than closing levels, there is no minimum block of downtime we need you to surrender.

Visually, most structures hold up for roughly a year before traffic film returns to where an owner notices it, with the entry ramp and ground level greying first because that is where every vehicle brakes and turns. Oil accumulation is driven by your tenants' vehicles rather than by the weather, so a garage with older cars or a service tenant loads faster. Coastal structures lose the exterior facade to salt drift well before the deck needs attention again.

It is the cheapest square footage on the property to improve and the first thing a tenant touches. A dark, stained, sour-smelling garage is a recurring complaint in tenant surveys and a live objection during a leasing tour, and neither is expensive to remove relative to the rest of an exterior budget. Cleaning also surfaces the things that are genuinely costly if missed (a failing traffic coating, a blocked drain, a spalling slab edge) while they are still small.
